Re: Starting New Process

Sorry, I should've specified - I'm familiar with sockets, but I was
referring to spawning a 'vi' process independent of my Python app..

Thanks, Jean-Paul - is there any way to do it without using Twisted,
since I am not very familiar with it? (i.e. just using the os library)
Thanks.

Hello, I need to write a server program that performs the following
tasks:

1) Listens on TCP port 5555 for a connection
2) When client connects, launches application (for example, vi), then
closes connection with client
3) Goes back to listening on TCP port 5555 for an incoming connection

Untested:

from twisted.internet import protocol, reactor

class ViRunner(protocol.Protocol):
def connectionMade(self):
reactor.spawnProcess(
None,
'/usr/bin/setsid',
['setsid', '/usr/bin/vi'])
self.transport.loseConnection()

f = protocol.ServerFactory()
f.protocol = ViRunner
reactor.listenTCP(5555, f)
reactor.run()

Use import socket ifyou don't want to use twisted (which is incredibly
good). Google for "+socket +python +server" and you will find what you are
looking for.

See, for example,
